China delays return of Shenzhou 20 crew due to possible capsule damage from “space debris”

11:02 pm

In a very brief statement today by China’s state-run press, it announced the planned return on November 6, 2025 of the Shenzhou-20 crew that has just completed their six month mission on the Tiangong-3 space station has been delayed indefinitely due to “a suspected impact from tiny space debris” on their Shenzhou capsule.

According to the statement “impact analysis and risk assessment are under way.”

A new crew arrived at the station on October 31, 2025 on the Shenzhou 21-capsule, and after a few days transition were to take over operations while the crew of Shenzhou-20 returned home.

We do not know the extent of the damage or even when it was first detected. Depending on the damage, China has several options. First, after review it could decide to return the crew on Shenzhou-20.

Second, it could decide that a fresh replacement capsule needs to be launched. If so, the old crew’s mission might be extended for a few months, as happened to a Soyuz crew on ISS in 2023 because of a leaking coolant system. First Russia launched a new empty capsule to ISS, and then the damaged capsule returned unoccupied. That way a lifeboat was always docked for that stranded crew.

It might also be possible to patch the damage, depending on its size and location.

In every case, the situation should not be critical. I am assuming the station is well stocked at this time, so that a crew of six instead of three could manage there for about three months. I am also assuming China has more Shenzhou capsules in the pipeline and can prepare a new one relatively quickly. Finally, I am also assuming China’s Shenzhou capsules can dock autonomously, as do their unmanned Tianzhou freighters.

And then again, if any of my assumptions are wrong, this situation could become more serious.

Sergio Mendes & Brasil ’66 – Mas Que Nada

6:01 pm

An evening pause: Performed on television c1966. They are clearly lip synching to the original recording, but the song is great, and the sets and dancing are worth watching, if only to get a feel for 1960s variety show television.

Hat tip Cotour.

Sunspot update: Solar activity continues to decline as predicted

3:46 pm

Another month has passed, and so it is time for my monthly update on the never-ending sunspot cycle on the Sun. using NOAA’s own monthly update of its graph of sunspot activity and annotating it with extra information to illustrate the larger scientific context.

The green dot on the graph below indicates the level of sunspot activity on the Sun’s Earth-facing hemisphere during the month of October. Not only did the number of sunspots decline from the count in the previous month, as predicted in April 2025 by NOAA’s panel of solar scientists (as indicated by the purple/magenta line), it dropped below their prediction.

  • Lawmakers warn UK must act now to get space ambitions back on track
    The report, by the House of Lords, is a joke. It says nothing about reducing regulation and red tape, which is the UK’s main problem. Instead, it proposes more funding and more government bureaucracy “to coordinate policy and industry engagement.” We should expect even less (lower than zero?) from the United Kingdom in the coming years.

Someone is apparently considering putting a helicopter on Starship when it goes to Mars

2:53 pm

Potential Starship helicopter location

In my regular trolling through the images sent down from Mars Reconnaissance Orbiter (MRO), I sometimes come across things that imply truly exciting future missions. That happened when in 2019 I found a bunch of photos each labeled as a “candidate landing site for SpaceX Starship”. Without fanfare SpaceX had begun researching locations for where it intended to land Starship on Mars, in the northern lowland plains, research that it later solidified considerably.

Similarly, I have found MRO images in 2022 suggesting scientists were thinking of running a helicopter mission inside Valles Marineris, the largest canyon in the solar system. Another image in 2024 suggested that a helicopter mission might go to another region in Mars’s southern cratered highlands.

The image to the right, cropped, reduced, and sharpened to post here, is another new example of a potential Martian helicopter mission. It was taken on August 19, 2025 and is labeled provocatively “Characterize Possible Rotorcraft Landing Site.” Unlike the previous two proposed helicopter locations, however — which appeared to be aimed at uncertain NASA funding — this image’s location suggests it is far more certain, and might launch far sooner than you can imagine.

More Washington shenanigans over who will be NASA’s next administrator

12:17 pm

Two news outlets in the past day (Politico and Ars Technica) have posted stories about a 62-page plan — supposedly written by Jared Isaacman while he was still the nominee to become NASA administrator — that was recently leaked to them as well as others inside and outside NASA.

The plan itself, dubbed “Project Athena”, has not been made available, though the descriptions at both sources suggest it matches closely with the overall Trump effort to cancel SLS and Orion and shift space operations out of NASA and more into the private sector.

The nature of this plan of course threatens NASA’s established work force and the big space contractors who have worked hand-in-glove with NASA for decades, producing little but distributing a lot of money and jobs to these groups. Not surprisingly, both news sources quote extensively from anonymous sources within that NASA work force and those big space contractors, lambasting the plan and blasting Isaacman for proposing it. From the Politic article:

Sean Duffy
Sean Duffy: “Pick me! Pick me!”

Putting all of these plans into writing is a “rookie move,” and “presumptuous,” said an industry insider who has seen the document and thought it would stoke congressional skepticism around his nomination. Many of these ideas would need congressional approval to enact, and Congress could always block them.

The Ars Techica article speculates that interim NASA administrator Sean Duffy was the source of the leak, in his effort to become NASA’s official administrator. If the plan is Isaacman’s, it generates opposition to renewing Isaacman’s nomination as NASA administrator while garnering support for Duffy from NASA’s workforce and those big space contractors.

All of this is pure Washington swamp, however, which really matters little in the long run. First of all, none of this is real. We are talking about an unreleased plan that no one has seen publicly, and the reactions of anonymous sources criticizing that unseen plan. It is all the stuff of ghosts and fantasy. For we know, it is all made up, just like the Russian collusion hoax was manufactured against Trump.

Second, and more important, who runs NASA next is becoming increasingly unimportant. » Read more

Intuitive Machines buys Lanteris, formerly Maxar

11:05 am

The lunar lander startup Intuitive Machines today continued its diversification into other space fields by acquiring the long-established satellite and spacecraft manufacturer Lanteris, formerly known as Maxar, for about $800 million.

The transaction is priced at $800 million, consisting of $450 million in cash and $350 million in Intuitive Machines Class A common stock, subject to adjustment. The transaction is expected to close in the first quarter of 2026, subject to customary regulatory approvals and closing conditions. As a stand-alone company, Lanteris is a cash generating business. As a combined company, Intuitive Machines expects to have adequate cash on hand for continued operations.

Intuitive Machines has attempted two lunar landings, both of which were failures when its lander fell over at touchdown. Since then it has made a concerted effort to diversify into other areas, including developing a returnable capsule, Zephyr, a lunar manned rover, Moon Racer, and an orbital tug. It has also acquired KinetX, a company specializing in space navigation and communications.

This new acquisition positions the company to bid on a much wider range of space projects, including military contracts relating to its Golden Dome project that is expected to cost billions.

First unmanned test flight of India’s Gaganyaan capsule likely slips to next year

9:47 am

Though India’s space agency ISRO still insists it will attempt the first unmanned orbital test flight of its Gaganyaan capsule before the end of 2025, its chairman has also indicated this schedule might slip into early next year due to agency’s upcoming launch schedule.

The problem is that it only has one launchpad for its largest rocket, LVM3 (recently nicknamed Bahubala) that Gaganyaan must use, and it has a contract with the American satellite company AST SpaceMoble to use Bahubala to launch one of its satellites next month. Furthermore, a Bahubala launch just occurred on that pad two days ago to launch a communications satellite for the Indian government. Thus, to do both the AST and Gaganyaan launches by the end of this year would mean it would have to do three launches from that pad in less than two months, something ISRO has never done.

ISRO plans to do at least three unmanned test flights of Gaganyaan before it attempts a manned orbital mission in 2027. If the first mission is slips into 2026, next year will be a very active one for ISRO, more active than that agency has been since it shut down during COVID.

Based on the present schedule, it appears that ISRO will set a pace of about one Bahubala launch every two months to complete this schedule, with the first Gaganyaan launch occurring around February 2026, and the next two Gaganyaan test launches in summer and fall. That would set the stage for the manned mission in early 2027.

MDA invests $7 million to become part owner of proposed Nova Scotia spaceport

9:29 am

Proposed Canadian spaceports

The Canadian space company MDA Space has now purchased for $10 million ($7 million in U.S. dollars) a part ownership in the proposed Spaceport Nova Scotia that the startup Maritime Launch Services (MLS) has been trying to establish since 2016, with little success.

The transaction includes an Investor Rights Agreement, entered into between MDA Space and Maritime Launch, providing MDA Space with certain rights, including the right to nominate one individual to sit on the board of Maritime Launch and pro-rata participatory rights in future financings of the Spaceport. The investment will be used for applicable research and development initiatives relating to the ongoing development of Spaceport Nova Scotia and will trigger the retirement of convertible debentures.

The history of this spaceport has been a frustrating one. Originally it had partnered with a Ukrainian rocket company, proposing to offer satellite companies both the launch facilities and the rocket. That plan died in 2022, when Russia invaded the Ukraine and the rocket company switched from making rockets to making drones.

MLS then opened up Spaceport Nova Scotia to all rocket companies, hoping the new launch startups building portable small rockets that could be set up anywhere would buy in. Though it periodically announced deals, none were with established orbital companies. Some were startups that after years have yet to launch, such as the British company Skyrora. Other contracts were with startups that weren’t even rocket companies, such as the space station startup Voyager Space.

Meanwhile, a second spaceport startup, Nordspace, appeared in 2022, proposing a spaceport in Newfoundland dubbed The Atlantic Spaceport. While it has not launched anything either, it has quickly signed contracts for ground stations and a mission control center, and even attempted (though scrubbed) a launch of its own rocket.

Whether this new deal can finally get Spaceport Nova Scotia off the ground remains very uncertain. MDA is not a launch company. It is a long established satellite company that also builds the robot arms used on ISS.

China will launch its upgraded manned Mengzhou-1 capsule in 2026

8:01 am

Mengzhou as of 2023

China this week revealed that it plans the first flight of its new larger Mengzhou-1 manned capsule next year, launching from its coastal Wengchang spaceport on its new Long March 10 rocket.

Mengzhou features a modular design consisting of a return capsule and a service capsule and will operate as the primary link between Earth and the space station.

The first flight of Mengzhou-1 will utilize the Long March-10A rocket from the Wenchang Space Launch Site in Hainan, targeting a docking with the space station’s core module radial port. This debut mission will validate the craft’s systems while transporting environmental monitoring devices, technical payloads, astronaut supplies, and experimental gear for science and technology demonstrations.

Both capsule and rocket are intended as China’s future mainstays for its manned program, both in Earth orbit and beyond. Mengzhou is intended as the manned capsule that will get its astronauts to lunar orbit, where its Lanyue lunar lander will take them to and from the surface. Both will be launched separately by the Long March 10 rocket.

Long March 10 has been in development since 2017, and will have the ability to place 70 tons in low Earth orbit and 27 tons to lunar orbit. It is thus comparable to SLS, but costing far less with its first stage incorporating recovery and reuse. It will also be capable of launching much more frequently and at a much faster pace.
